    • Workaround:
      Either disable fast integer division --idiv_support=none, or if using fast integer division, --idiv_support=idiv0, avoid using the specific case for the I64/UI64 fast integer division.
    • Release Notes:
      Hide
      For the C2000 fast integer division feature, --idiv_support=idiv0, FPU register loads could incorrectly move ahead of the ABSxxDIVxx instruction in a fast integer division sequence.

      This could only happen for the I64/UI64 fast integer division case.
